Definitions
- the present invention relates to two-way radios and, g ⁇ >r-e particularly, to a portable two-way radio with a removable RP module and improved means for connecting accessories to the radio and module.
- a portable radio can be provided with an accessory comprising a small remote microphone and speaker (and,, perhaps, a remote antenna) whereby the user can communicate through the small hand-held accessory while keeping the larger portable radio affixed to a belt, or, the portable radio can fit into an automobile adaptor which connects the radio to the automobile"s battery and antenna system, thereby turning a hand-held portable radio into a more powerful mobile unit.
- The- roblem of accessory adaptability further complicates the problem of keeping the radio compact and light weight. This is because it is desirable to have all external radio connections made at one location on the radio, albeit through multiple electrical connections through a single multi-pronged electrical plug (commonly referred t ' as a "universal device connector") configured to mate with cooperating radio contacts. Heretofore, this has necessitated the routing of some RF circuitry through the control section of the radio to the external connection point, further necessitating complex shielding arrangements to insure that any RF radiation leakage does not interfere with the control signalling.
- a portable two-way radio comprises two modules.
- One module is a controls systems module containing the controls necessary to operate radio functions such as volume and channel control, push-to-talk (PTT) button, keyboard, speaker, microphone, and others.
- the other module is the RF module containing the transmitter and receiver portions of the radio, including the antenna. The portion of the radio to which the universal
- 1 device connector is connected is split, with 'those contacts associated with the control functions (to which they are electrically connected) being located on the exterior of this control systems module casing.
- the universal device contact associated with the RF module namely, the RF connector
- the universal device connector contacts associated with both modules are located physically adjacent to each other on their respective modules suchr. that a single multi-pronged universal device connector (UD.C) can be electrically connected to both the RF and control systems modules.
- U.C multi-pronged universal device connector
- the RF module is removably connected to the control
- the RF module comprises a hollow rear cover casting having an integral upstanding web around its periphery which is received by the control systems module front casting to ensure proper component alignment, weather sealing and to carry structural 5 loads.
- a transeiver component board is sandwiched and captured between honeycomb shielding integrally formed on the inside of the rear cover casting and a separate honeycomb casting which provides further shielding of the RF components on its side of the transceiver board. All electrical
- connection between the RF and control modules occurs through a multi-pin interconnector associated with the control module and a cooperating male bus connector on the RF module's tranceiver board. Because of the unique split UDC connector arrangement, it is unnecessary to route any portion of the RF
